Abstract
Introduction: Pneumothorax is defined as the presence of air in the pleural space. Spontaneous pneumothorax, occurring without antecedent traumatic or iatrogenic cause, is classified as primary or secondary. There are substantial inconsistencies in international guidelines for the treatment of pneumothorax. Moreover, many geographical variations exist in daily clinical practice.Areas covered: In this article, we focus on novel treatment modalities for this significant health problem in young adults.Expert opinion: In part, these discrepancies have been caused by the lack of high-quality trials or evidence. Currently, the pathophysiological mechanisms underlying pneumothorax are better understood and have implications for clinical management. Studies have demonstrated that the judicious use of pleurodesis can decrease its rate of recurrence, both in surgical and nonsurgical patients.

Abstract
Abstract
Primary spontaneous pneumothorax (PSP) is one of the most common thoracic diseases affecting adolescents and young adults. Despite the high incidence of PSP and the availability of several international guidelines for its diagnosis and treatment, a significant behavioural heterogeneity can be found among those management recommendations. A working group of the Italian Society of Thoracic Surgery summarized the best evidence available on PSP management with the methodological tool of a systematic review assessing the quality of previously published guidelines with the Appraisal of Guidelines for Research and Evaluation (AGREE) II. Concerning PSP physiopathology, the literature seems to be equally divided between those who support the hypothesis of a direct correlation between changes in atmospheric pressure and temperature and the incidence of PSP, so it is not currently possible to confirm or reject this theory with reasonable certainty. Regarding the choice between conservative treatment and chest drainage in the first episode, there is no evidence on whether one option is superior to the other. Video-assisted thoracic surgery represents the most common and preferred surgical approach. A primary surgical approach to patients with their first PSP seems to guarantee a lower recurrence rate than that of a primary approach consisting of a chest drainage positioning; conversely, the percentage of futile surgical interventions that would entail this aggressive attitude must be carefully evaluated. Surgical pleurodesis is recommended and frequently performed to limit recurrences; talc poudrage offers efficient pleurodesis, but a considerable number of surgeons are concerned about administering this inert material to young patients.

Abstract
BACKGROUND Primary spontaneous pneumothorax (PSP) is a relatively common clinical entity with high incidence in the young population. Video-Assisted Thoracic Surgery (VATS) bullectomy and chemical or mechanical pleurodesis are two primary modalities of treatment. There has been much debate on the ideal mode of pleurodesis, but the literature on surgical outcomes comparing VATS pleurectomy with talc pleurodesis has been inconclusive. METHODS We performed a single-centre 5-year observational retrospective study of 202 patients who underwent VATS bullectomy with talc pleurodesis or parietal pleurectomy. RESULTS There were no significant differences in the demographics, pre-operative and intra-operative characteristics in both groups. Recurrence of pneumothorax, chest tube duration and hospital stay were similar in both groups. However, talc pleurodesis had a shorter operative time compared to pleurectomy. CONCLUSION Our study demonstrated comparable outcomes between talc pleurodesis and pleurectomy following VATS bullectomy for patients with PSP.

Abstract
Background and Objective Most patients with giant pulmonary bulla (GPB) are treated by surgery; however, there is a subset for whom surgery is not a viable option, such as those with contraindications, or those unwilling to undergo operation. Therefore, an alternative minimally invasive method is desired for this subpopulation. The aim of this study was to explore an alternative procedure for treating GPB. Methods This was a prospective, nonrandomized, single-arm, unblinded study evaluating the efficacy and safety of intrabulla adhesion pexia (IBAP) procedure in GPB patients. The study was conducted between December 2004 and April 2017. Results There were 38 cases in 36 patients (33 males and 3 females) with the target GPB cavities varying in size (range, 10 cm × 7 cm × 5 cm to 15 cm × 8 cm × 30 cm (anteroposterior diameter × medial-lateral diameter × superoinferior diameter)). After IBAP treatment, the closure ratio of GPB in one month was 86.84% (33/38), while the dyspnea index significantly decreased from 4.11 ± 1.11 to 2.24 ± 1.15 (P < 0.01). In addition, the mean FEV1 (L) increased from 1.06 ± 0.73 to 1.57 ± 1.13 (P < 0.01), while RV (L) decreased from 2.77 ± 0.54 to 2.36 ± 0.38 (P < 0.01) and TLC (L) decreased from 6.46 ± 1.21 to 5.86 ± 1.08 (P < 0.01). Moreover, PaO2 (mmHg) increased from 52.18 ± 8.31 to 68.29 ± 12.34, while the 6 MWD increased by 129.36% from 131.58 ± 105.24 to 301.79 ± 197.90 (P < 0.01). Collectively, these data indicated significant improvement in pulmonary function and exercise tolerance after IBAP treatment. Furthermore, no deaths occurred during IBAP treatment, and no cases of aggravated GPB relapse were reported during the 12-month follow-up period. Conclusions IBAP is a promising strategy for the treatment of GPB. Our findings demonstrated that IBAP had a noteworthy therapeutic effect, desirable safety, and ideal long-term efficacy for GPB.

Abstract
Objectives Spontaneous pneumothorax is a common pathology. International guidelines suggest pleurodesis for non-resolving air leak or recurrence prevention at second occurrence. This study comprehensively reviews the existing literature regarding chemical pleurodesis efficacy. Design We systematically reviewed the literature to identify relevant randomised controlled trials (RCTs), case–control studies and case series. We described the findings of these studies and tabulated relative recurrence rates or ORs (in studies with control groups). Meta-analysis was not performed due to substantial clinical heterogeneity. Results Of 560 abstracts identified by our search strategy, 50 were included in our systematic review following screening. Recurrence rates in patients with chest tube drainage only were between 26.1% and 50.1%. Thoracoscopic talc poudrage (four studies (n=249)) provided recurrence rates of between 2.5% and 10.2% with the only RCT suggesting an OR of 0.10 compared with drainage alone. In comparison, talc administration during video-assisted thoracic surgery (VATS) from eight studies (n=2324) recurrence was between 0.0% and 3.2%, but the RCT did not demonstrate a significant difference compared with bleb/bullectomy alone. Minocycline appears similarly effective post-VATS (recurrence rates 0.0–2.9%). Prolonged air leak and recurrence prevention using tetracycline via chest drain (n=726) is likely to provide recurrence rates between 13.0% and 33.3% and autologous blood patch pleurodesis (n=270) between 15.6% and 18.2%. Conclusions Chemical pleurodesis postsurgical treatment or via thoracoscopy appears to be most effective. Evidence for definitive success rates of each agent is limited by the small number of randomised trials or other comparative studies.

Abstract
Our study sought to determine whether the size of the residual apical pleural space in young patients with primary spontaneous pneumothorax (PSP) following video-assisted thoracoscopic surgery is associated with the risk of recurrence. We retrospectively reviewed patients (≤30 years' old) with primary spontaneous pneumothorax following thoracoscopic surgery (2002-2010) in a university-affiliated hospital. The size of residual apical pleural space was estimated by measuring the apex-to-cupola distance on a postoperative chest radiograph at 2 time windows: first between postoperative day (POD) 0 and 3, and second between POD 4 and 14. A total of 149 patients were enrolled with a median follow-up of 11.2 months (interquartile range, 0.95-29.5 months), of whom 141 (94.6%) were male with a mean age of 20 years. The postoperative recurrence rate was 11.4%. Comparing the characteristics between the patients with and without recurrent pneumothorax, the patients with recurrence were younger (18.2 + 2.4 vs 20.7 + 3.7 years, P = 0.008), with a lower rate of pleurodesis (35% vs1 69%, P = 0.037), longer apex-to-cupola distance at POD 0 to 3 (22.41 ± 19.56 vs 10.07 ± 10.83 mm, P < 0.001) and POD 4 to 14 (11.82 ± 9.75 vs 5.54 ± 8.38 mm, P = 0.005) than the patients without recurrence. In a multivariate logistic regression model for recurrent pneumothorax, age <18 years (P = 0.026, odds ratio [OR]: 4.694), apex-to-cupola distance at POD 0 to 3 >10 mm (P = 0.027, OR: 5.319), and no pleurodesis during VATS (P = 0.022, OR: 5.042) were independent risk factors for recurrent pneumothorax. The recurrence rate was not low (11.4%) in young patients with PSP following VATS. Residual apical pleural space with apex-to-cupola distance of 10 mm or greater at POD 0 to 3, younger age, and no pleurodesis would increase postoperative recurrence of primary spontaneous pneumothorax.

Abstract
BACKGROUND Giant emphysamtous bulla (GEB) can negatively affect the pulmonary functions of chronic obstructive pulmonary diseases (COPD) patients, including decreased forced expiratory volume in 1 s (FEV1) and increased functional residual capacity (FRC). The aim of this study was to evaluate the efficacy of endobronchial valve (EBV) to treat bullae and to find efficacy predictors of successful treatment. METHODS Five COPD patients with giant bulla were treated using EBVs. Before the EBV deployment, collateral ventilation (CV) between the targeted and adjacent lobes was evaluated with Chartis system. RESULTS In the two patients with negative CV, the mean value of FEV1 increased from 27.1±11.4% of predicted value before EBV treatment to 32.8±12.0% (P>0.05) at 1 month after EBV treatment, than to 31.7±24.5% (P>0.05) at 6 months after EBV treatment. Only one patient, whose bulla occupied the whole right middle lung, displayed sustained improvement of FEV1 at 6 months after EBV treatment. In the three patients with positive CV, the mean value of FEV1 decreased from 28.8±19.0% of predicted value before EBV treatment to 24.8±12.6% (P>0.05) at 1 month after EBV treatment, than to 22.1±10.8% (P>0.05) at 6 months after EBV treatment. CONCLUSIONS EBV is an effective measure to treat highly selected COPD patients with giant bulla. Although, EBV treatment can achieve transient improvement of lung function at patients with CV negative bulla, long-term benefit was merely observed at the patient with a bulla at right middle lobe (RML).

Abstract
PURPOSE OF REVIEW The role of chemical pleurodesis in the treatment of primary spontaneous pneumothorax remains unclear. According to current practice guidelines, chemical pleurodesis is reserved for patients who are unable or unwilling to have surgery. Some recent studies showed that intrapleural minocycline pleurodesis could decrease the rate of pneumothorax recurrence, when used either as the initial treatment for simple pneumothorax after successful aspiration and drainage or as an adjuvant treatment for complicated or recurrent pneumothorax following thoracoscopic surgery. The purpose of this review is to discuss the current available evidence on intrapleural minocycline pleurodesis for the treatment of primary spontaneous pneumothorax. RECENT FINDINGS In a recently published prospective, randomized controlled trial, additional minocycline pleurodesis following simple aspiration and drainage was a well tolerated and more effective initial treatment for a first episode of primary spontaneous pneumothorax than simple aspiration and drainage alone. Other prospective, randomized controlled trials showed that additional minocycline pleurodesis after thoracoscopic treatment was a well tolerated and convenient procedure which can reduce the rate of ipsilateral recurrence of primary spontaneous pneumothorax. SUMMARY Intrapleural minocycline pleurodesis can be considered an adjunct to standard treatment of primary spontaneous pneumothorax, after either simple aspiration and drainage or after thoracoscopic surgery.

Abstract
Pneumothorax is defined as the presence of air in the pleural cavity. Spontaneous pneumothorax, occurring without antecedent traumatic or iatrogenic cause, is sub-divided into primary and secondary. The severity of pneumothorax could be varied from asymptomatic to hemodynamically compromised. Optimal management of this benign disease has been a matter of debate. In addition to evacuating air from the pleural space by simple aspiration or chest tube drainage, the management of spontaneous pneumothorax also focused on ceasing air leakage and preventing recurrences by surgical intervention or chemical pleurodesis. Chemical pleurodesis is a procedure to achieve symphysis between the two layers of pleura by sclerosing agents. In the current practice guidelines, chemical pleurodesis is reserved for patients unable or unwilling to receive surgery. Recent researches have found that chemical pleurodesis is also safe and effective in preventing pneumothorax recurrence in patients with the first episode of spontaneous pneumothorax or after thoracoscopic surgery and treating persistent air leakage after thoracoscopic surgery. In this article we aimed at exploring the role of chemical pleurodesis for spontaneous pneumothorax, including ceasing air leakage and preventing recurrence. The indications, choice of sclerosants, safety, effects, and possible side effects or complications of chemical pleurodesis are also reviewed here.
